D'Alembert strategy for crash games

The D’Alembert strategy in crash games is simple: add one unit after a loss and take one unit off after a win, never going below one unit. It is a gentle progression system that pairs naturally with a 2x auto cash out in Aviator, Stake Crash or JetX. In our 1,000-session test with GH₵20 units it finished with a median of GH₵620 from GH₵1,000, with the top 10% on GH₵2,020 or more. Here’s how to run it on SportyBet Ghana, Betway Ghana or a partner crypto casino, with cedi examples. More systems in our crash game strategy guide.

How the D’Alembert system works

The rule: add one unit after a loss and take one unit off after a win, never going below one unit. Here is how six rounds play out at 2x auto cash out with a GH₵20 unit:

Round	Stake	Result	Running profit
1	GH₵20	Loss	−GH₵20
2	GH₵40	Loss	−GH₵60
3	GH₵60	Win at 2x	GH₵0
4	GH₵40	Loss	−GH₵40
5	GH₵60	Win at 2x	GH₵20
6	GH₵40	Win at 2x	GH₵60

The stake moves with your results, which is the whole idea: the system decides your next bet so you never have to.

D’Alembert simulator test in cedi

We ran the D’Alembert system at 2x through our simulator: 1,000 sessions of up to 100 rounds, a GH₵1,000 bankroll and GH₵20 bets. The median session finished on GH₵620, the luckiest 10% on GH₵2,020 or more and the coldest 10% on GH₵0 or less. 44.9% of sessions ran the bankroll below one bet. For comparison, flat GH₵20 bets at 2x finished on a median of GH₵960 with 0% busts. Try your own settings in the crash game simulator.

What D’Alembert does well

• Stakes climb one unit at a time, far slower than Martingale.
• Every win pulls the stake back down, so hot streaks stay cheap.
• Easy to run in your head between rounds.

Worth knowing:

• A long cold run still builds the stake step by step.
• Wins at 2x pay the current stake, so a win after a climb only claws back part of the run.
